No opinion on the reference, but out of curiosity I hunted down the equivalent man page on a RHEL system. There it goes by ctype.h(0P), which makes some kind of sense: there isn't a ctype function, so it has no business in section 3, while wctype is a function so there is a wctype(3) along with a header page wctype.h(0P). 0P seems to be for POSIX headers, or something like that. BSDen don't seem to bother with this distinction and just provide ctype(3). -- Thomas Munro https://enterprisedb.com
